| Unsustainable exploitation of wild animals is one of the greatest threats to biodiversity and to millions of people depending on wild meat for food and income. The international conservation and development community has committed to implementing plans for sustainable use of natural resources and has requested development of monitoring systems of bushmeat offtake and trade. Although offtake monitoring systems and indicators for marine species are more developed, information on harvesting terrestrial species is limited. Building on approaches developed to monitor exploitation of fisheries and population trends, we have proposed two novel indicators for harvested terrestrial species: the mean body mass indicator (MBMI) assessing whether hunters are relying... |

| Marine protected areas are a laboratory of integrated coastal management. Driving the MPA system requires the implementation of a battery of indicators of governance. This governance must take into account both the internal dynamics of the system and the threats coming from the system environment. As part of a research project funded by the French Ministry of Ecology, (Liteau program), 4 coral reef MPAs were selected as pilote studies (St Martin in the Caribbean, Reunion and Mayotte in the Indian Ocean, the South Lagoon of New Caledonia in Oceania) to develop jointly between scientists and managers of MPAs governance indicators. The approach is definitely bottom up. It is based on the co-construction of indicators. In that way, the views of the scientists... |

| The trophic level mean and variance, and the degree of omnivory for five Celtic Sea fish predators were estimated using a database of stomach content records characterized by a high level of taxonomic resolution. The predators occupied a high position in the food web, i.e. 4.75 for Atlantic cod Gadus morhua, 444 for haddock Melanogrammus aeglefinus, 4.88 for European hake Merluccius merluccius, 5.00 for megrim Lepidorhombus whiffiagonis and 5.27 for whiting Merlangius merlangus. The level of taxonomic resolution of the prey did not greatly affect mean T-L predator values; an effect on variance was evident, low resolution masking intra-population variability in T-L. Generalized additive models (GAM) were used to explain the variability of predator T-L... |

| Fishing pressure on reef fish stocks, in relation to exploitable biomass, is a useful parameter for fishery resource management but difficult to assess in subsistence fisheries. A methodology for indirect fishery output assessment in island environments is proposed based on estimates of consumption and the relevant seafood trade. Ouvea atoll in the South Pacific (Loyalty Islands, New Caledonia), where subsistence fishing is the main activity, was used as the IPF experimental site. A consumer survey of the islands' households was conducted in June 2000. The sampling plan was determined on the basis of data already available on the population concerned, making it possible to give quantitative and qualitative information on catches. Total catch is estimated... |

| Within the European water framework directive (WFD), the status assessment of littoral waters is based both on the chemical quality and on the ecological quality of each water body. Quality elements enabling to assess the ecological status of a water body are, among other things, biological quality elements (phytoplankton, macroalgae, angiosperms, benthic invertebrates, fish), for each of which the member states have developed quantitative indicators. This document is one of the deliverables of a multi-annual study intended to characterize the sensitivity of these biological indicators towards the various anthropogenic pressures exerted on the French Atlantic and Channel coast: ultimately, the goal is to establish a quantitative and predictive... |

| - The AMBIO project conducted a comprehensive video-based baseline assessment of coral reef fish communities and associated habitats in the New Caledonian lagoons. The survey relies on remote unbaited underwater video observations, using the STAVIRO rotating technique. - The study pertains to the reefs of Astrolabe, Pétrie and Walpole Island, located within the Coral Sea Natural Park. The survey conducted in 2014 covers the entire area, and the sampling design was stratified according to reef type. 95 stations were validated. They were analyzed to characterize the habitat surrounding each station, and fish communities, based on a list of 565 fish species (cf. AMBIO/A/1). - 28 indicators were computed and mapped (maps available on a Sextant server).... |

| While the majority of small-scale coastal fisheries are found in developing nations, a considerable number exist in developed nations as well. Indeed, small-scale fisheries are strongly represented in all European Union (EU) Member States, 81% and 87% of the EU 25 whole fleet is composed of vessels less than 12 and 15 meters long respectively. In 2000, European regulation established a fisheries data collection framework including economic information requirements in order to provide the scientific basis for the implementation of the Common Fisheries Policy. This paper presents the methodology designed to collect the relevant economic data and characterize the status of the French fleets from an economic perspective. Based on stratified sampling plan... |

| 1. Abiotic and biotic variables of coastal lagoons are highly heterogeneous in both space and time, and this heterogeneity complicates the assessment of their ecological status. These variables are essential to the monitoring and preservation of these fragile ecotones and the resources and services they sustain. 2. An integrative approach for evaluating the ecological status of coastal lagoons, based on field investigations of the key parameters driving their functioning and a set of selected ecological indicators matching lagoon management information needs for societal benefits, is investigated. Consistency in lagoon status evaluation from multiple and different variables was estimated, through a case study comparing three adjacent yet contrasting French... |

| Coastal areas are complex socio-ecosystem where ecological, human and decisional compounds show multiple and reciprocal relationships. Because of the growth of population and tourism sector, coastal areas are permanently threatened through increase of recreational uses and diversification of related activities. To better understand coastal areas functioning, it is necessary to take into account uses and their management. Monitoring data over a ten years period revealed that recreational uses greatly increased especially within Marine Protecting Areas (MPA), during week-end days and warm season resulting to higher and more frequent frequentation peaks. While, practices within MPA are managed to decrease impacts, pressures associated with recreational uses... |

| Using the Celtic Sea and the North Sea as case studies, the fleet-based approach is shown to be the pathway to implement an effective ecosystem approach to fisheries management (EAFM) in European seas. First, a diagnostic on the health of each ecosystem is proposed based on the reconstruction of long time-series of catch, the analysis of mean indicators or stocks trajectories derived from ICES stock assessment results, and the analysis of ecosystem indicators. Then, a fleet-based synthesis is presented using indicators of both the ecological impact and the economic performances of the major fleets operating within each ecosystem. In particular, assessment diagrams show whether each fleet segment, on average, sustainably exploits the stocks. Although... |

| Introduction : Quality attributes of fish flesh, including food safety, organoleptic features, nutritional quality and aptitude to industrial transformation, influence consumption and acceptability of fish as food. Fish sensorial changes and texture properties are closely linked to freshness. Along with ante mortem muscle biochemistry, postmortem biochemical processes are directly linked to final quality attributes. The understanding of postmortem mechanisms is a prerequisite for an accurate control of the quality of commercialized fish by the identification of objective markers or indicators. Postmortem tenderization is one of the most important quality attributes of fish muscle. Loss of freshness is due to a complex combination of biochemical, chemical... |

| From the 1980's, Indonesian shrimp production has continuously increased through a large expansion of cultured areas and an intensification of the production. As consequences of diseases and environmental degradations linked to this development, there are currently 250,000 ha of abandoned ponds in Indonesia. To implement effective procedure to undertake appropriate aquaculture ecosystem assessment and monitoring, an integrated indicator based on four criteria using very high spatial optical satellite images, has been developed to discriminate active from abandoned ponds. These criteria were: presence of water, aerator, feeding bridge and vegetation. This indicator has then been applied to the Perancak estuary, a production area in decline, to highlight the... |

| The necessity to move from a traditional fishery management to an ecosystem approach is now acknowledged. Indicators are required to support the development of this approach. For example, community indicators have been proposed to assess the impact of fishing. We tested here the applicability of one such community indicator, the abundance-biomass comparison (ABC method), as a measure of the impact of bottom trawling (years of sampling: 2001 and 2003) on the benthic invertebrates-typically starfishes, crabs, squat lobsters, shrimps and large hard-shelled molluscs-of "Grande Vasiere", a major French fishing zone, in the Bay of Biscay. The ABC method is generally used as an impact indicator for different types of physical, biological and anthropogenic... |
